THREAD GUIDING AND SUPPORTING MEANS FOR SPINNING AND TWISTING. MACHINES.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed September 1906- Sflfial To all whom it may concern:

Be it known that I, J onN E. Pnnsr, a citizen of the United States,residing in Melrose, county of Middle sex, and State of Massachusetts,have invented an Improvement in Thread Guiding and Supporting Means forSpinning and Twisting Machines, of which the following description, inconnection with the accompanying drawing, is a specification, likeletters on the drawing representing like parts.

This invention has for its object to improve the class of thread guidesupporting means shown in U. S. Patent N 0. 758,933, dated May 3, 1904.In that patent and others of which it is a type, the inner end of theguide eye at the underside of the finger board is covered by a shield orguard held in operative position by a bolt, flanges at the oppositeedges of the. shield contacting with the under side of the finger board.The finger board in practice has to be stopped in its operative orhorizontal position, and stopping of the finger board has been effectedin various different ways.

In accordance with my present invention, I have, by a change in theshape of the shield also made it operate as a down stop for the fingerboard.

Figure 1 in front elevation shows part of a roller beam and threadboard, with two finger boards, one of the latter being turned up, andFig. 2 is a section on the line :0, Fig. 1, but with the finger board atthe left turned down.

In the drawing, A represents part of the usual roller beam, B part of anangular thread board presenting at its front side a flange B andconnected to the roller beam by hinges b, and the roller beam has a stopa to arrest the thread board in its horizontal or operative position.The finger boards 0 are of sheet metal bent to present side flanges 2, 4and an end flange 3, the sheet metal forming the finger board being bentat its inner end opposite the flange 3 to form circular eyes 5. The eyes5 are separated to embrace a hinge member D slotted at (Z to receive ascrew d that may be inserted through a hole in the downturned flange ofthe thread board where, see Fig. 2, a nut 6 is applied to said screw.The shank of the thread i guide E is passed through the flange 3, andsaid shank,

see Fig. 1, is covered by a stop shield F, the latter being confined tothe finger board by a bolt and nut in usual manner.

In accordance with my invention I have so shaped the stop shield that itpresents flanged side edges and a tail piece f extended and offset tocross said rod G, the end of the tail piece contacting, said tail-pieceserving to position the upper sides of the boards in the horizontalplane of.the top of the thread board, said tail piece, as hereinrepresented, contacting with the hinge member D when the finger boardoccupies its horizontal or operative position, see Fig. 2, and forms adown stop for the finger board. The effective strength of the stopshield is increased by the contact of its outer end, see Fig. 1, withthe flange 3 of the finger board. When about to assemble the parts andsupport the finger boards on the thread board, the finger boardsuspending rod G will be thrust through say the right hand ear 5 of eachfinger board, then through the eye at the upper end of a series of rodsustainers D, then through the other or left hand eye 5 of the fingerboard, one after the other. This done, the hinge members are placedagainst the front side of the thread board and the screws d are insertedin the slots d and the finger boards and rod sustaincrs are thenadjusted longitudinally on said rod, said slots (1 permitting, and thefinger boards having been adjusted to bring the guide eyes of eachfinger board into proper operative relation to the spindles, then thescrews will be tightened to hold the rod sustainers and finger boards intheir true operative relation.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. In apparatus of the class described, a threadboard, a series ofindependent hinged members connected with said threadboard, a series offinger boards mounted to turn about said shaft, a guide-eye for eachfinger board, and a stop shield connected with each finger board and c0-acting' with said guide-eye, each stop shield having a tailpieceprolonged and off-set to cross the axis of said shaft and serve as astop to maintain said finger boards in their horizontal positions.

2. In apparatus of the classdescribed, a thread-board, a series ofindependent hinged members connected with said .thread-board, a seriesof finger boards mounted to turn about said shaft, a guide-eye for eachfinger-board, and a stop shield formed of sheet metal presenting sideflanges and having a tail-piece oft-set and prolonged beyond saidflanges sufficiently to cross the axis of said shaft, the end of eachtail-piece meeting a hinged member when the finger boards occupy theirhorizontal operative positions.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing' witnesses.

JOHN E. PRIEST.
